What roll does the gastric mill play in digestion in a crayfish?
Wiki User
∙ 16y ago
In crustaceans, specifically decapods such as the crayfish, the stomach is divided into two parts: the first, or anterior part is called the "gastric mill". The gastric mill is lined with chitinous teeth which grind up coarse food particles. The posterior part of the stomach acts as a filter to keep coarse particles from entering the digestive glands, where absorption takes place.
